  摘要：This article proposes a probabilistic framework for the design of robustly asymptotically stable moving-horizon estimators (MHE) for discrete-time nonlinear systems, and a mechanism to incorporate differential privacy in moving-horizon estimation. We formulate the moving-horizon estimator as an iterative proximal descent scheme in the space of probability measures with respect to the L-2-Wasserstein metric, which we name W-2-MHE. We then investigate asymptotic stability and robustness properti...
• Distortion-Based Lightweight Security for Cyber-Physical Systems AI翻译

  摘要：In cyber-physical systems (CPS), inference based on communicated data is of critical significance as it can be used to manipulate or damage the control operations by adversaries. This calls for efficient mechanisms for secure transmission of data since control systems are becoming increasingly distributed over larger geographical areas. Distortion-based security, recently proposed as one candidate for secure transmissions in CPS, is not only more appropriate for these applications but also qui...
• Variational Adaptive Kalman Filter With Gaussian-Inverse-Wishart Mixture Distribution AI翻译

  摘要：In this article, a new variational adaptive Kalman filter with Gaussian-inverse-Wishart mixture distribution is proposed for a class of linear systems with both partially unknown state and measurement noise covariance matrices. The state transition and measurement likelihood probability density functions are described by a Gaussian-inverse-Wishart mixture distribution and a Gaussian-inverse-Wishart distribution, respectively. The system state vector together with the state noise covariance mat...

  摘要：This article presents a computational framework to efficiently generate feasible and safe trajectories for multiple autonomous vehicle operations. We formulate the optimal motion planning problem as a continuous-time optimal control problem, and approximate its solutions in a discretized setting using Bernstein polynomials. The latter possess convenient properties that allow to efficiently compute and enforce constraints along the vehicles' trajectories, such as maximum speed and angular rates...
• Bounded Synchronization of Heterogeneous Complex Dynamical Networks: A Unified Approach AI翻译
  作者：Zhu, Shuaibing; Zhou, Jin; Yu, Xinghuo; Lu, Jun-an
  作者单位：Wuhan University; Royal Melbourne Institute of Technology (RMIT)
  摘要：This article addresses the bounded synchronization of heterogeneous complex dynamical networks. Different from most existing criteria which deal with only global bounded synchronization, a general theorem is established for analyzing both the local and global bounded synchronization of a class of heterogeneous networks in a unified approach. By developing a joint-diagonalization-like technique, several easy-to-use bounded synchronization criteria with low-dimensional linear matrix inequalities...
• A General Framework for Switched and Variable Gain Higher Order Sliding Mode Control AI翻译
  作者：Incremona, Gian Paolo; Rubagotti, Matteo; Tanelli, Mara; Ferrara, Antonella

  摘要：Sliding mode control is a widely used approach in different application domains, due to its versatility and ease of implementation. As is well known, one of its most serious drawbacks is the presence of chattering. To alleviate this problem, higher order sliding mode (HOSM) approaches have been proposed, which also allow dealing with high relative degree plants. To gain more flexibility in the controller design and to boost performance, switched and variable-gain approaches are being developed...
• Moving-Horizon Estimation for Linear Dynamic Networks With Binary Encoding Schemes AI翻译
  作者：Liu, Qinyuan; Wang, Zidong
  作者单位：Tongji University; Tongji University; Shandong University of Science & Technology; Brunel University
  摘要：This article is concerned with moving-horizon state estimation problems for a class of discrete-time linear dynamic networks. The signals are transmitted via noisy network channels and distortions can be caused by channel noises. As such, the binary encoding schemes, which take advantages of the robustness of the binary data, are exploited during the signal transmission. More specifically, under such schemes, the original signals are encoded into a bit string, transmitted via memoryless binary...
• Distributed Integer Balancing Under Weight Constraints in the Presence of Transmission Delays AI翻译
  作者：Rikos, Apostolos, I; Hadjicostis, Christoforos N.
  作者单位：Royal Institute of Technology; University of Cyprus
  摘要：We consider the distributed weight balancing problem in networks of nodes that are interconnected via directed edges, each of which admits a positive integer weight. A digraph with positive integer weights on its edges is weight balanced if, for each node, the sum of the weights of the incoming edges equals the sum of the weights of the outgoing edges. In this article, we develop a distributed iterative algorithm, which solves the integer weight balancing problem in the presence of arbitrary (...

  摘要：The general context of this article is the feedback control of an infinite-dimensional system so that the closed-loop system satisfies a fading-memory property and achieves the setpoint tracking of a given reference signal. More specifically, this article is concerned with the proportional-integral (PI) regulation control of the left Neumann trace of a one-dimensional reaction-diffusion equation with a delayed right Dirichlet boundary control. In this setting, the studied reaction-diffusion eq...

  摘要：In this article, we study a constrained optimal control problem for an ensemble of control systems in a centralized setting. Each system evolves on a matrix Lie group, and must satisfy given state and control action constraints pointwise in time. In addition, the controller must be shared between the plants in the sense that at any time instant the control signal may be sent to only one plant while minimizing a given objective function. We provide first-order necessary conditions for optimalit...
